I was exaggerating, certainly. Fact is, that "multi-lingual" printers  
take the %! as the marker for a PostScript print job following.  
Otherwise they would have some trouble to distinguish the stream from  
PCL or ASCII input.

Besides, as claimed before, "%!" starting in the first column of the  
first line of a file is recorded as marker for PostScript code before  
PostScript Level 3. Everyone who comes later should obey.

GNU Emacs' understanding of "%!" is as crude as that of CUPS (was).
